Distributed Services Management Toolkit
• The Problem– we have: cool virtual machines, cool locations in the
Internet, cool resource allocation systems, cool distribution systems
– no framework for integrating their use
• The Solution: DSMT– Installation and monitoring system– Framework for managed resource use– Node selection and control– Plug-ins for interesting research areas:
» distributed application management, » resource negotiation» container installation

DSMT
• Create a framework for distributed application operation
– Selection of resources
– Allocation and provisioning of resources
– Installation and running of application instances
– Monitoring of application operation
• Base services– Event messaging systems (PsEPR)
– Generalized ‘application manager’

DSMT Goals
• Wrap services with existing services– Structure which includes resources allocation,
resource negotiation, PLC interface, …
• Solves “first problems”– Allocation of PlanetLab nodes and slivers– Installation of application components– Monitoring application operation– Collection of results data– Termination
• Targeted at new PlanetLab users

Distributed Service Deployment and Monitoring
• PI creates managed slice– dsmtc create –slice my_slice –user PLuser
• Application writer makes application installable– rpmgen –file ball.tar …
– dsmtc depot put rpmfile
– dsmtc setagent –agent deployment-agent
• Slice user specifies destinations– dsmtc setplan –base sword –plan myplan [email protected]
refresh=3600
• Run monitor to view PsEPR status events

DSMT Evolution Plans
• Version 1: May– Solve PlanetLab first app problem– sample solution based on YUM and centralized service planner
• Version 2: September– Long term, complex services– Success = we win 3 existing services– Web Services based (GGF CDDLM standard) application
specification– Address service dependencies, service-based APIs
• Version 3: December– models and adaptation– open APIs for service composition
• Version 4:– distributed models
